To all whom it may concern.-

Be it known that l, GEORGE W. GLAZIER, of Salem, in the county of Essexand Commonwealth of Massachusetts, have invented certain Improvements inGluing-lllachines, of which the following, taken in connection with theaccompanying drawings, is a specification.

This invention relates to mechanism for gluing pasteboard and otherarticles, of which boxes and similar articles are made; and the natureof this invention is fully described hereinafter, and fully pointed outin the claims.

Referring to the drawings, Figure 1 is a View looking down upon themachine from one side at an angle of about forty-five degrees, andillustrates the top and side of the machine. Fig. 2 is a similar view ofthe glue distributing mechanism detached from the machine. Fig. 3 is adetail view, on line x as of Fig. 1, showing the bearing for thefeedroll, the said feed-roll, together with the gluedistributing rollbeing shown in dotted lines. Fig. 4 represents a vertical section infront of the main driving-shaft, some of the parts be ing in sideelevation.

The glue pan or basin is made in the usual and customary way ofconstructing glue-pans, and is designated in the drawings by the letterA. It is to be provided with legs, if desired, and has anoutwardly-extended brim, A, as shown, thus adapting it for use on itslegs; or, if desired, it may be depressed into a suitable opening in thetop of a table or bench in the usual way. It is to be heated by hotwater brought into contact therewith in any obvious manner, asheretofore practiced. Connected to the said glue-pan A is a plate, B,which may be fixed to the pan or temporarily attached thereto by bolts,as shown. Said plate B has two vertical posts, a a, in the upper ofwhich is mounted the shaft I). The lower portions of the parts areextended horizontally to form bearings for a shaft, (1, as shown. Shaftb carries on one end the wheel 0, and receives motion from the shaft clthrough intermediate gears, 3 46, the wheel being thus revolved in thedirection indicated by arrow 6. The corrugated wheel D, that takes upthe glue and co-operates with wheel 0 to feed forward blanks, is fixedupon the short studshaft 10, on the opposite end of which stud is fixedthe small pinion 7, the stud being journaled in the frame or plate H, tobring the gear into engagement with the gear on pinion 6 on the end ofshaft (1. By this arrangement the motion of shaft (Z is lransmitted towheel D to revolve it, as indicated by arrow f.

It will be obvious that the wheels D C are caused to revolve in oppositedirections relatively to each other, as indicated by the arrows 6 f, orreversely, according to the motion of shaft (I. Said wheel D takes upand distributes the glue, while the wheel (J, being in close proximitythereto, bears upon the top side of the blank and helps to move the samealong. I

It is of course desirable to feed through the wheels many differentthicknesses of material, and to this end I mount the shaftb in a box orblock, it, one end of which is connected to post a by a swivel-pin, It,while the opposite end is fitted to slide vertically up and down in thepost a, as shown, thus allowing the wheel C to lift and accommodate theblanks without regard to thickness thereof. On the top of post a is acap, m, and under the cap is a spiral spring that surrounds the screwor, and'bears upward against the cap and downward against the block h,thus keeping the wheel pressed downward upon the top of the material, tohelp move the same forward.

In rear of wheels 0 D is the guide-plate 8, that is shown in thedrawings as clamped to the block or plate by means of screws t t, and isthus rendered not only detachable from the block, but adjustable towardand from the wheels 0 D. 1t operates as a guide to the edge of the blankwhileit passes through the wheels, and may be secured directly to orformed integral with the block,though I prefer to make it adj ustable,as stated and as shown. Said plate or block H is further provided witharms or wipers 12 and 13, that reach forward to thewheel D, as shown,though not being allowed to quite touch the same. They operate toprevent the glue from rising too thickly or in lumps on the wheel D, andthus distributing the glue evenly.

In operating the machine,the wheel D is depressed into the glue held bybasin A, and is allowed to run with more or less of its lower edge inthe glue. Said wheel takes up the glue by contact therewith, and thesame is first distributed evenly by wipers 12 13, as described againstthe blank being fed along, deposits theglue along the edge of the blank,and also cooperates with the wheel 0 to move forward the blank, asbefore stated.

To insure a sufficient deposit of glue, I prefer to groove orcuttheperiphery of the wheel D, as shown, as a larger deposit of glue isthereby secured, allowing the machine to be run at greater speed.

It is not intended that wheel 0 should at any time come into contactwith wheel D, as it would thereby get covered with glue, and thus damagethe top edge of the blank; but to further provide against evenaccidental contact with glue I provide the wiper 16,to bear upon thewheel and keep it cleaned.

It will be understood that in operating the machine theglue-distributing mechanism will get covered with glue that cools andhardens; also, that the glue-wheel is depressed into the glue, and ifleft there over night will be locked in by the'hardening of the glue. Iconsider it therefore of great advantage to have these parts detachablefrom the machine, and to this end I mount the glue distributingmechanism on the single block or plate H, as represented in Fig. 2, andthis plate I attach to the machine, as shown in Fig. 1, the post a inthis figure being broken away in its center to illustrate the manner ofclamping the block to the basin, for which purpose any ordinaryclampscrew, 14, may be used. By this arrangement the glue-distributingmechanism may be readily removed and placed in water whilethe glue 5 issoft, and thus be cleaned, and also prevent being locked into the gluewhich cools in the glue-pan.

I claim- 1. In a gluing-machine, the combination of 0 the suitableframe, and the wheel 0 mounted thereon,and a glue-distributing wheelmounted upon the plate or block, said plate or block being removablysecured to the frame of the machine above the glue-pot, substantially as5 described.

2. In a machine for pasting blanks, of substantially the constructiondescribed, the block or plate H, having mounted thereon the guard 8, thewheel D, and wipers for said wheel, all 30 substantially as stated, saidblock H being adapted to be attached to the main parts of the machineand detachable therefrom, substantially as described.

3. In agluing-machine, the shaft b, adapted 55 to permit verticalmovement at one end, the wheel 0, mounted on said end, and a springarranged to depress the shaft and yield upward, as and for the purposesstated.
